Definitions

• the present invention relates to tricyclic compounds and intermediates thereof with a side chain having an anilino moiety having an acyl coenzyme A: cholesterol acyltransferase (hereafter referred to as ACAT) inhibiting activity.
• ACAT cholesterol acyltransferase
• Cholesterol is supplied in vivo by biosynthesis and absorption. Compounds which inhibit biosynthesis and absorption might reduce cholesterol level in blood serum. As compounds having an activity of inhibiting absorption, nicotinic acid derivatives and sterols originated from plants are known. However, their activity is not sufficient.
• Cholesterol is absorbed on epithelial cells of the intestine in its free form, then esterified by ACAT, included in chylomicron, and transported to liver by blood stream in chylomicron form.
• ACAT plays an important role in accumulation of cholesterol in liver.
• ACAT is also involved in transformation of macrophage to foam cell.
• ACAT is thought to cause progression of arteriosclerosis [J. Lipid Res., 26 , 647 (1905); Nippon Rinsho (Clinic in Japan), 47 , 554 (1989)].
• Compounds which inhibit ACAT might inhibit the absorption of cholesterol and accumulation of cholesterol in liver. Therefore, these effects accelerate excretion of cholesterol and consequently reduce cholesterol level in blood serum. Furthermore, such compounds inhibit the formation of foam cells and are thus expected to be effective for the treatment of hyperlipemia and arteriosclerosis.
